A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...

A critical comparison of methods for the determination of phytoplankton chlorophyll

Creator:: Salinas, John T.
Abstract:: The concentration of chlorophyll in natural bodies of water is commonly determined as a means to rapidly estimate the phytoplankton biomass. The literature gives numerous warnings, however, as to the problems involved with accurately determining chlorophyll concentrations. The author's work at Crater Lake, Oregon enticed him to explore critically the...

Development of automated flow injection apparatus and a novel flow cell for chemi- and bioluminescence determinations

Creator:: Gander, Stuart C.
Abstract:: A practical and versatile instrument has been developed both to optimize the chemistry of bio- and chemiluminescence reactions and to measure ultra-trace quantities of associated analytes. The instrument consists of a pneumatic flow injection system linked to a detection cell and a signal processing and readout system. The disk-like cell...

Part I : development and application of an arsenic speciation technique using ion-exchange solid phase extraction coupled with GFAAS ; Part II : investigation of zinc amalgam as a reductant

Creator:: Bos, Mark C.
Abstract:: Two related techniques, based upon ion-exchange solid phase extraction, have been developed for the determination of arsenic speciation. The inorganic arsenic species arsenite (As(III)) and arsenate (As(V)) are separated by anion-exchange and detected with graphite furnace atomic absorption spectrophotometry (GFAAS) with a nickel matrix modifier. The first separation technique, which...

The determination of gasoline and alkyl benzenes in aqueous solution and the development of a remote reaction chamber for fiber optic remote sensing

Creator:: Waddle, Robert D.
Abstract:: The development and optimization of a single-phase derivatization technique for small ring aromatics in water are presented. Also described are the design, optimization and application of a remote reaction chamber for fiber optic sensing. Aqueous solutions of the major aromatic compounds in gasoline are derivatized to o-nitrosophenol-Cu complexes with a...

Evaluation of sampling/preconcentration techniques and pyridine derivative reagents for fluorometric determination of chloroform and TCE in water

Creator:: Prayoonpokarach, Sanchai
Abstract:: A direct purge technique was developed for the determination of chloroform or trichloroethylene (TCE) in water samples. These volatile organic solvents are transferred from the water sample to a reagent where they are trapped and react to form products (Fujiwara chemistry) that are monitored fluorometrically. Chloroform in a water sample...

Speciation of inorganic arsenic by hydride generation atomic absorption spectroscopy

Creator:: Ikeda, Marcia Sakiko
Abstract:: A sensitive technique for the determination of As(III) and As{V) at μ/L and sub-μg/L concentrations from a single sample aliquot has been developed. This technique is based on the hydride generation atomic absorption (HGAA) spectrophotometry. The hydrides of the arsenic species are generated in a reaction vessel by mixing the...
